Now as we know the pollution in the cities is becoming more and more serious and it is bad for humans' health.So it is important for us to discuss how to protect the environment .
First we can sort the litter.Second we can reuse newspaper and glass.Third maybe we can landfill harmful litter to protect they harm our health.Fourth we must treat waste water treatment better.Fifth the government can make some laws to provent some unethical merchants.Sixth we can invite some teenagers and some volunteers to help us propaganda to let people enhance the conscious of protecting the environment.
In a word,it is our duty to protent the environment .If anybody can relize it,Ithink that our life will become more and more beautiful and graceful.
Thank you for listening.
